1. A stent comprising:

  • a stent body defining a proximal end, a distal end, and a longitudinal axis extending from the distal end to the proximal end, the stent body being expandable from a compressed configuration to an expanded configuration, the stent body including a plurality of stent segments,wherein the stent segments include a first end segment and a second end segment on opposite ends of the stent body and at least one intermediate segment disposed between the first end segment and the second end segment,wherein each stent segment defines a plurality of cells,wherein the first end segment defines a plurality of peaks and valleys, the distance between a peak and an adjacent valley of the first end segment being equal to a first length,wherein the at least one intermediate segment defines a plurality of peaks and valleys, the distance between a peak and an adjacent valley of the at least one intermediate segment being equal to a second length,wherein the first length is longer than the second length,wherein, for each of the plurality of the peaks and the valleys of the first end segment, a distance between the peak and the adjacent valley is longer than the second length,wherein the first end segment includes a first circumferential row of struts and a second circumferential row of struts defining cells of the first end segment, the second circumferential row of struts being directly adjacent to the first circumferential row of struts,wherein the first circumferential row of struts defines a first peak and a first valley, wherein the second circumferential row of struts defines a second peak and a second valley, wherein the first peak points away from a longitudinal center of the first end segment and the first valley points towards the longitudinal center of the first end segment, wherein the second peak points towards the longitudinal center of the first end segment and the second valley points away from the longitudinal center of the first end segment, andwherein the first circumferential row of struts and the second circumferential row of struts are connected to each other between the first valley and the second peak, the connection between the first valley and the second peak being substantially parallel to the longitudinal axis of the stent body.
